I think it's a joke, but the admins and all the staff over at Friendcodes is taking this seriously. I just thought I'd spread the word across the other Nintendo websites that I'm registered at what's going on.

Sadly, I believe you. I was once a former member of Nintendo NSiders before it was shutdown. On that forum, there was absolutely no FC sharing allowed. It could get you banned in a flash. So, I really wouldn't be surprised at this.
